There seems to be some confusion about the meaning of “chance” - which is not surprising because it is used with five different meanings:
"1
a**:** something that happens unpredictably without discernible human intention or observable cause
b : the assumed impersonal purposeless determiner of unaccountable happenings
: luck <an outcome decided by
chance>
c : the fortuitous or incalculable element in existence
: contingency
2**:** a situation favoring some purpose
: opportunity <needed a
chance to relax>
3**:** a fielding opportunity in baseball (or cricket)
4
a : the possibility of a particular outcome in an uncertain situation;
also : the degree of likelihood of such an outcome <a small
chance of success>
b plural : the more likely indications <
chance**s are he’s already gone>
5
a : risk <not taking any
chance**s>
b : a raffle ticket

chance adjective
—
by chance : in the haphazard course of events <they met
by chance>"

“By chance” is obviously equivalent to non-design but in the context of the entire universe it is clearer to use “Chance” (or non-Design) in contrast to “Design” - like Jacques Monod who entitled his book
Chance and Necessity:
"One may well find oneself beginning to doubt whether life is “**the product **of an enormous lottery presided over by natural selection, blindly picking the rare winners from among numbers drawn at utter random.” (p.138)
In spite of this concession he concludes:
“Pure chance, absolutely free but blind, at
the very root of the stupendous edifice of evolution… is today the sole conceivable hypothesis, the only one that squares with observed and tested fact.” (ibid.) !
The issue is not the process but the initial state and the outcome: the existence of purposeful beings.
It is absurd to allow our lives to be ruled by incalculable elements which don’t know what they are doing. It is equally absurd to believe all knowledge is produced by elements which know precisely nothing! That is a metaphysical conjuring trick almost as fantastic as the belief that everything is derived from precisely nothing…
